Serial No. 402,398.

To all whom it may concern:

Be it known that I, Arowlo E. linoAnns, a citizen of the United States, and. resident of-I-Iopedale, county of'Wm-eester, State of Massachusetts, have invei'itod an- Improvement in Thread. Parting Mechanism for Looms, of which the following description, in connection with the accompanying draw-- ing, S a specification, like letters on the draw in representing like parts.

' his invention relates more particularly to automatic looms wherein the running filling is replenished prior to completeexhaustion, and t0 the mechanism for parting the old filling-end near the shuttle, such fillingsend extendin from the cloth to the shuttle containing t v d filling-supply or bobbin about to be abandoned.

-In United States--Patent' No. 683423 2 0 granted September 24, 1901'to C. H. Dra. er

mechanism is provided to clamp the old lling-end and part it near the shuttle, the clamped end then being drawn forward to bring it into range of the temple tl1readcut ter so that the latter may sever the end close to the cloth. The clamping of the filling-end was positive, and in on er to prevent breakage of the end when the parting and clamping mechanism returne 'l to normal position means were provided in said patent to move such mechanism in a diagonal path toward the edge of the cloth, thereby relieving the clam ,ed end from strainand preventing 'brea age.

Myrpresent invention has-for its objectthe production of novel means-for effecting the movement of the clamping andpartin mechanism toward the cloth after the ol filling-end has been parted and while it is clamped. v Thecla'm ing and parting means ismounted on the siuttlevfeeler, and I have also so constructed and arranged the apparatus that the feeler moves complete] y across the mouth of the replenisl ingbox when the shuttle is properly positioned then-in for replenishment;

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is 'a transverse section, on the line 11, Fig. 2, of a suflicient portion of a loom, with my present invention applied thereto, the shutt e-.feeler, a,nd the means for shuttle-box; Fi 6 is a detail 'of 't cutting blades as close-as I plane pi the back wall of the 0X, to hold-the closed. r

cl aniping and parting the old filling-end, being shown in normalinoperative position; Fig. 2 is a top plan view of the mechanism illustrated in Jig. 1, but with the lay farther forward; Fig. 3 is a view similar to'Fig -1' so but showing the feeler in operative position across the mouth of the re le'nishingshuttle box, and just before the clhnipin and"),arting means operated; Fig. 4' is a rent ieve tion of the feeler, the carrier on which it isss mounted, and the controller to'govern lateral 'I1'lOV6l'l16'nt of the feeler, said controller-being in section; Fig. 5 is a detailv 'infrontelev'a tion' of the inner end of the replenishing device, to be re erred toi.

Referring to the drawin s, the lay At, havr ing itsraceway transverse recessed ate; ad? jacent the mouth of there enishingfshu'ttlebox- B, the transferrer f-"il ig'. 1, fu1c1 ume d" atfand adapted to remove the filling carrie rs or bobbins 6* from the filli'ngfeeder (partly shown in Fig. 1) and the centrelling nook-shaft (1, may be and areof welilhnown construction. '-f-'80 Herein I ha've shown the back Wallb of the" shuttle-110x15 as provided with arr-upright opening 1)", Fig; .5, in line with the recess i the top plate?) bein TeXtended'oversu-ch openin the purpose'po the latter bein" to re" ceive t e extremityor tip' of,"thefsfhttl feeler when the shuttle S. is prbpeny-boxsd, 1 so that thefeeler can xtendfcompletely across the mouth; of the box, as 'sho'w'njin Fig. 3, and carry-the openingfbetweenthe'te O SSl ble 'tt) ftlid thread securely trapped when jth'e blades'are,

In the present embodiment of "my l'n v tion a bracket 1 on the loom side has ahori zontal, inwardly extended stud 2- olijwhio mounted the hub 3 of arather. shed up turned arm or carrier 4,.shownzin Fi' 4 slightly bent Iaterally'ahd having itsap st" l end enlargeiil to form aIboss carrying-' stud 6 at ri ht angles to the stud 2 U this stud is lulcrumed the enlarged and at tened end 7 of an inclined, upturned'sha nkfi' terminating in a rearward extension consti j fore and-aft direction with the carrier 4 I e setting 70 tuting the shuttle-feeler 9., The fewer-the also being adapted to swing or rock relatively thereto upon the stud 6 as a fulcrum, as Wlll be manifest. An upturned lug or follower 10 on the feeler travels in an inverted trough-like cam or cont-roller 11, rigidly secured to the-breast-beam A, the controller being curved in the direction of its length, Fig. 2, and it is also curved or arched slightly in side elevation, Figs. 1 and 3.

Referring to Fig. 2 it .wilLbe seen that the groove in the controlleris substantially at right angles to the lay at its rear end, as at 11, (see dotted lines) so that the final move ment of the feeleracross the lay will be in a direct line and straight across the mouth of the shuttle-box.

When filling-replenishment is called for the carrier 4 is swung rearward on its fixed fulcrum 2 to the osition shown in Fig. 3, and it carries the fee or with it, but as the follower 10 travels along the cam-like controller 11 the feeler will be moved laterally on its fulcrum 6 from its normal, inoperative position shown in full lines, Fig. 2, into position directly opposite the recess a on the lay and the opening I), as in dotted lines Fig. 2. Thus the feeler is moved away from the edge of the cloth as it is moved to operative position', and u on return movement the reverse action is eiiected, the'feeler moving toward the edge of the cloth, for a purpose to be explained hereinafter. The swinging movement of the carrier may be effected by any desired means, and herein I have shown a extended between jawike members 13, 14 controlled by a spring 15 and moved. operatively by the rock-shaft (1 when the latter is turned to eifect the operation of the relenishing mechanism, as in United States atent No. 846700 granted March 12, 1907 'to Smith and Stimpson.

Upon the feeler 9 I mount suitable means" to clamp and part theold filling-end when the and I have chosen for illustration means for the purpose substantially as shown in United States atent N 0. 834269 granted October 30, 1906 to Cunnifl'.

The ti of the feeler 9 is notched at 9" to receive tie filling-thread when the feeler is moved into operative position asshown in Fig. 3, the igpper and lower edges of the notch beln-g 'shown as flared, to better direct the 'thre' d to the cutting blades, the fixed blade I 16, e dotted. lines Fig. 3, being secured to -the feeler adjacent the lower edge of the notch, while the movable blade 17 is fulcrumed on ie stud 18, and cooperates with the blade 1 to part the thread while cooperating Withethe plate 19 which constitutes the fixed member of the clamp, as in the ()unnifi' patent l'eferred to.. The movable member 17 is thus apart of the clamp and also a part of the means for parting the filling, its

in 12 on the carrier feeler is operativelypositioned as described,

heel 20 being struck by the advancing lay, to first clamp the iillin'g-cnd. and then to part it at the sidetoward the shuttle, the end remaining clamped when thol'eeler returns to normal, inoperative position, Fig. 1. But

during such return movement the lcclcr blades, to successively clamp and part the thread, the notched tip of the feeler is extended through the opening I) in the back wall of the box, and the extremities of the blades 16 and 17 project rearward slightly beyond the plane of the front face of said back wall. As a result the thread to be parted is trapped in what is practically a closed space, for it crosses the opening I) and between the edges of the blades and hence cannot escape when said blades are closed, as the box wall holds the thread from rearward movement and the blades prevent it from moving up or down, or forward, out of the opening between their edges.

As the elmnpiug and parting device is closed when thefeeler is 111 normal position such device must be set or opened before it is operatively positioned to cooperate with the old fillingwnd, and herein the setting device is mounted on a bracket 21. depending from the controller or cam 11, the bracket having pivoted to it at 22 a short arm 23-, Fig. 6, provided with a cam rib .24. A spring 25 acts to maintain said rib in lifted position, the spring being shown. in dotted lines Fig. (5, a stop pin 26 limitingupward l'uovcment. of the arm 23., the movable member 17 of the thread (lamp and parter is adapted to pass under the rib A lateral pin 27 on the heel of- I 21 as the leeler nioves rearward to operative position, the rib then acting to swing the member 17 into open position. After the clamp has been closed the pin 27 wipes-over the top of the rib 24 as the feelor returns to normal position, thearm :23 being swung downward against the action of spring 2.. as the pm 27 passes over the r1b,-so that no opening movement of the clamp is effected. .Tllls setting device 111 its general construction is substantially the same as shown in the Draper patentNo. 683423 referred to. r

So far as my present invention is concerned the particular mechanism forclamping and parting the old filling-end may be of any desiredmharzuter and construction, that shown herein being for purposes of illustration; and

so, too, the means for swinging the carrier on which the feeleris mounted may be changed. Having to lly described my invention, what 'I claim as new and desire to secure by Let-' ters Patent is 1. In an automatic filling-replenishing loom, a swinging carrier, a'shuttledeeler pivotally mounted thereon and laterally movable relatively thereto, means carried by the feeler to clamp and part the thread of the filling-supply to be abandoned, and means to contro and cause it to move toward the edge of the cloth as the carrier returns to normal posi-.

Wardly prior to filling replenishment, a shut-- tle-feelertpivoted on the carrier to rock laterally an also to move bodily with the carrier, a controller to govern the lateral movement-of the feeler-and cause it to approach the ed e of the cloth as-the carrier returns to norma position, and means mounted on the --feeler to clamp and part the thread of the filling-su ply to be abandoned, the combined rearwar movement of the carrier and the lateral rockingof the feeler operatively positioninlg said means to act u on the thread.

an automatic fil lug-replenishing loom, a lay havinga shuttle-box, a swinging carrier, means to move it toward the lay when replenishment is called for, a shuttlefeeler p1votally,'mounted on and movable with the carrier and also laterally relatively thereto, to cross the mouth of the shuttlebox when the shuttle is properly boxed, a fixed controller cooperating with the feeler, to govern its lateral movement when moved forward or back by the carrier, and means on the-feeler to clamp and part the thread of the filling-supply to be abandoned when replenishment is effected, the controller causing the feeler to move-laterally toward the edge of y -the cloth when the carrier returns to normal position, to prevent breakage of the clamped end of filling.

4, In a loom, automatic filling-replenishing mechanism, a lay, a shuttle-box thereon at the replenishing side having an opening in the lateral movement of the feeler its back wall adjacent the mouth of the box, aeshuttled'eeler, thread parting means thereon, and. means acting automatically when replenishment is called for to move the feeler .into position to'cross the mouth of the shuttle-box and enter the opening in its back Wall when the shuttle is properly boxed, to

thereby cause the arting means to extend across the plane 0 the back wall and trap the thread to be parted.

5. In an automatic filling-replenishing loom, an upturned, swinging carrier, means to move it rearward when replenishment is called for, a shuttle-feeler pivotally mounted onthe carrier, to move bodily therewith and also laterally relatively thereto, a fixed cam to govern the lateral movement (If the feeler, a follower on the latter cooperating with the cam, means on the feelcr to clamp and part the thread of the filling-supply to be aljea ndoned, and a device mounted on the cam to set the clamping and parting means when the feeler is moved into operative position, v

the cam aeting,upon return of thecarrier to normalposition, to move the feeler toward the edge of the cloth. s I

6. In an automatic filling-replenishing loom, means bodily movable in a diagonal path, upon filling replenishment, to aet'u on and clampJ and part the thread of the filhngsupplyto .e abandoned, return of said means to normal position toward the edge of the cloth reventing breakage of the clamped end 0 filling; combined with a sup ort for said means, comprising two pivota ly connected members one of which is ada ted to swing automatically in a path para'lle to the edge of the cloth and the other transversely to the path of movement of the first memher, and means to control the transverse movement of the second member.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
